History doc covers: ENUM-vs-CHECK rationale (plan was written against
the wrong primitive — actual gate is the language_code ENUM from
migration 001), machine-translation seed + [needs review] marker,
ICU-placeholder parity verification, locale-keys diff script
contract, and the ParaglideJS {#key lang}-on-navigation cross-cutting
gap that constrained the shape of EU-01.
Test deltas: pgTAP +5, integration +2, unit +4, e2e +2 — 581 + 3
skipped (was 568 + 3). Documents the pre-existing 010_sync_conflicts
flake (offline.test.ts e2e contamination) as out of scope for Fase 20.
CHANGELOG gains the [Unreleased] entry. Moves into [v1.0.0] in the
release commit.
